About the formats
BMP (Windows Bitmap, 1990) is a simple, uncompressed Windows format. Files are large because every pixel is stored as-is, but almost any program, including very old software and embedded devices, can read it.
PDF (Portable Document Format, 1993) is the universal document format. A PDF looks the same on every device and printer, which makes it the safest way to send images as documents, forms or scans.
Frequently asked questions
How do I convert BMP to PDF?
Drop your BMP files into the box above (or tap Select files), check the options, then press Convert. Each PDF downloads on its own, or you can download them all as one ZIP file.
Are my files uploaded anywhere?
No. The conversion runs entirely in your browser on your own device. Your BMP files are never sent to a server, so they stay private, and it works even on a slow connection once the page has loaded.
Is there a limit on how many BMP files I can convert?
No. Convert as many as you like, for free, without signing up. Very large batches are processed one after another so your browser stays responsive.
Can I put several BMP images into one PDF?

Does it work on iPhone and Android?
